Bobcat T250 2003 Parts Catalog – Factory Specs You Can Bet on

I’ve been turning wrenches since before some of you were born. Twenty-eight years in the shop, ASE Master, and I still won’t touch a Bobcat T250 without the factory parts catalog in reach. The 2003 edition here – 361 pages, printed for serial numbers 5231 11001 and above – is exactly what you need if you’re tired of guessing which filter or cartridge goes where. That OCR snippet on page 3 shows part numbers for inner and outer air cleaner cartridges (6681474 and 6681475), plus part 6678233 for an engine oil filter six-pack. That’s the kind of data you can’t trust from aftermarket cross-reference sheets.

Maintenance Items: What the 361 Pages Cover

Page 2 through 5 lay out the Bobcat T250 2003 Parts Catalog maintenance items and service schedule. The manual breaks down intervals at 10, 50, 250, 500, and 1000 hours. At 10 hours you’re checking motor oil weight options – 10W30, 15W40, or straight 30 CE/SG – and swapping inner/outer air cleaner cartridges. The parts catalog lists the exact OEM numbers: 6681474 for inner, 6681475 for outer. I’ve seen guys grab a generic NAPA filter that fits but bypasses the pre-cleaner. Don’t be that guy. Buy the right part the first time from the factory spec list.

Service Schedule Items – When to Check What

At 50 hours you add hydrostatic fluid and hydraulic fluid to the checklist. The manual calls out part 6563328 for a 2.5-gallon jug, or 6722344 for five gallons. Page 314 is where the fluid specs live – engine oil, hydraulic/hydrostatic fluid, and grease. If you’re working on a T250 turbo and you don’t know the correct viscosity for the hydraulic system, you’re risking seal blowouts. This parts catalog gives you the exact Bobcat part numbers for bulk drums too: 6563330 for a 55-gallon drum. That’s not a service manual – it’s a parts catalog. But it shows you precisely which consumables to order.

Parts Numbers and Cross-References: OCR Excerpt Reality

The OCR from the real document shows part numbers like 6657301 for 1-quart 10W30 motor oil, and 6658266 for general purpose grease. You see that in the “Service Schedule Items” section starting on page 4. Each item has a reference page. The fuel element is part 6667352 – page 44. The hydrostatic element (inner) is 6661248 – page 120. These aren’t approximations; they’re the numbers Bobcat stamped on the box. I’ve ordered the wrong cartridge before because I used a third-party catalog. This OEM parts catalog fixes that. It’s 361 pages of verified factory data, not a recompiled PDF from a scan farm.

Why OEM Matters for a 2003 Bobcat T250

Aftermarket parts catalogs skip serial number splits. This one covers S/N 5231 11001 & Above (track loader) and S/N 5230 11001 & Above (wheel loader variant?). The turbo T250 has specific engine and hydrostatic components. Page 3 lists the battery – 6665427, 950 amp. If you slap in a 700-CCA battery from AutoZone, you’ll be cranking slow on cold mornings. The OEM catalog tells you exactly what the factory installed. That’s why I tell every shop owner: buy the factory documentation. Check out the Bobcat T250 2006 Service Manual for later model updates, or the Bobcat T250 2008 Service Manual if you’re working on a newer machine. For this 2003 parts catalog, stick with the S/N range.

7 Systems Documented in the Parts Breakdown

This catalog covers the loader frame, engine assembly, hydrostatic drive, cooling system, electrical, cab/ROPS, and hydraulic attachments. The maintenance items section alone lists 17 distinct part numbers for filters, fluids, and cartridges. Each one has a reference page in the main body. You want the HVAC filter? Part 6677983. That’s on page [DATA NEEDED] – the OCR doesn’t show the page, but the manual’s index will get you there. The point is, this is a complete parts breakdown, not a “general reference”. It’s the same book Bobcat dealers used to order parts in 2003.

FAQ

Is this a service manual or a parts catalog?

Parts catalog. 361 pages of factory part numbers and exploded views, not step-by-step repair procedures.

Can I use this to rebuild the engine on my T250?

It will show you every OEM part number for the engine – pistons, rings, gaskets, oil cooler – but it won’t tell you torque specs or clearance limits. You need a service manual for that. For example, the engine oil filter six-pack is part 6678233, but you won’t find the torque for the filter housing here. Pair this with the Bobcat T3571, T3571L 2005 Parts Catalog – OEM Factory Specs if you’re working on similar models.

Does this cover the turbocharger assembly?

Yes. The T250 Turbo model includes turbo-specific part numbers. The OCR shows “TURBO” on page 1. The exhaust side components, oil lines, and boost lines are listed in the engine section. You’ll need to search the parts index for “turbocharger” or “exhaust manifold.”

What serial numbers are covered?

Two ranges: S/N 5231 11001 & Above (track loader), and S/N 5230 11001 & Above (wheel loader variant). Verify your machine’s serial number before ordering parts. The manual was published in August 2003 (date code 8-03).

This 361-page original factory print is the exact documentation Bobcat shipped to dealers. If you’re sourcing parts for a 2003 Bobcat T250 turbo, you don’t want a generic cross-reference. You want the parts catalog that lists every nut, washer, and filter by OEM number. That’s what you get here. Access the Factory Manual and keep it in your shop tablet or print the pages you need. Your machine will thank you. For a broader look at the Automotive Industry Overview, understand that factory documentation like this is the backbone of proper maintenance.
